ITW Shakeproof industrial


The Taptite is a tri-lobular thread forming screw. The mating threads are work-hardened as they are formed. Because of the tri-lobular shape, material pushes back around the screw due to elastic recovery. This helps the screw to resist loosening due to vibration.


    • Reduces the amount of chips during thread forming
    • Provides a strong joint with perfectly mating threads
    • Eliminates the need for separate tapping processes

Available Features:

    • GER-NIB® – for particularly torque sensitive applications
    • SEMS – add a washer under the head to span larger holes, protect fragile surfaces, and distribute load.
